MORRIS HANOWER, OF EOET LEE, NEW JERSEY, ASSIGNOR TO THE EAGLE PENCIL COMPANY, OF NEW YORK, N. Y.

oOMeAss ATTACHMENT FOR PENCILS.

SPECIFICATION forming part of Letters Patent No. 376,379, dated January 10, 1888.

Application filed October 25, 1887. Serial No. 253.289. (No model.)

To all whom it may concern.-

Be itknown that I, Monnrs HANOWER, of Fort Lee, in the State of New Jersey, have invented a new and useful Improvement in Compass Attachments for Pencils, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is a view of my improved device with the parts so arranged that the device may be used as a pencil. Fig. 2 is a view of the same with the parts in the position they 0ccupy when used as a pair of compasses or dividers. Fig, 3 is adetached view of the needle-point. Fig. 4 is a like view of a modified formof needle-point. Fig. 5 is an axial section through the hinge which unites the two tubular sections of the device.

The two tubular sections,which form in one position the handle of the pencil and in another position the legs of the compass, are shown at A B. One of them, A, is to receive the pencil P, and for this purpose is made of a pattern similar to any ordinary or suitable pencil-holder. In the present instance it con sists of a longitudinal split sheet-metal tube, which receives and clasps the pencil. The other tube, B, is to receive the needlepoint.

The needle-point (shown in Figs. 1, 2, and 3) is a sheet-metal shell of a size to fit in the tube B, having a tapered outer end terminating in the needle (1. At its other end is a block or cylinder, b, of rubber or other erasive material. A convenient way of holding this device in place is to provide it with a laterally-projecting pin or stud, c, which will enter and engage one of the series of notches (1, formed in one edge of the longitudinal slit or slot 6 in tube B. The shell 0 isinserted in the tube B, the pin passing along through the slot 6 until it comes opposite the notch with which it is to be engaged, and then by a slight turn of the shell the pin is caused to enter the notch, thus holding the shell in place. The shell 0 is reversible, so that either its rubber end. or its needle end can be exposed, according as the device is to be used as a pencil, Fig. 1, or as a pair of compasses, Fig. 2. In lieu of this device, a needle-point--such as shown in Fig.

4-can be used, consisting of a simple cylindrical wooden stick, D, armed at one end with a needle, and adapted to be inserted and held in the tube B in the same way as the pencilP is in tube A. The stick, like the shell 0, is reversible.

The tubes A B are hinged together in such 0 which has its ends headed, so as to prevent the lateral spreading of the ears. Surrounding the pin it is the spiral spring 2', which is closely compressed between the two inner ears, 9 g, and consequently by its expansion holds these cars closely and tightly against the outer ears, ff, the ears being of sheet metal and sufficiently flexible to permit of this action. In this simple and effective way apermanent and lasting friction hingejoint is secured,whereby the tubular sections A B, while they can be moved by hand with relation to each other, will be most securely. and firmly maintained in their adjusted position, thus rendering unnecessary the use for the purpose of set-screws or tightening-nuts, which require manipulation at each change in the adjustment of the parts.

It will be noted that the axis h of the hinge is so placed that it lies in the plane of the joint formed by the meeting or abutting ends of the two tubes when they are in the position shown in Fig. 1.

Having described my improvement, what I claim herein as new and of my invention is-- 1. The combined compass and pencil consisting of the split pencil-holding tube A and the tube B and the reversible needle-point fitting in the same, said tubes being formed and proportioned and hinged together, in the manner. described, so that when they are fully unfolded their adjoining ends will abut, and tially as and for the purposes hereinbel'ore set x the two will form in effect a continuous straight forth.

tubular pencil handle. In testimony whereof I have hereunto set my 2. The combination, with the two sections hand this 22d day of October, 1887.
